This is the default installation program for FreeBSD, although vendors are free to provide their own installation suite if they wish. This chapter describes how to use Sysinstall to install FreeBSD. After reading this chapter you will know: How to create the FreeBSD installation disks. How FreeBSD refers to, and subdivides, your hard disks. How to start Sysinstall. The questions Sysinstall will ask you, what they mean, and how to answer them. Before reading this chapter you should: Read the supported hardware list that shipped with the version of FreeBSD you are installing, and verify that your hardware is supported. Pre-installation Tasks Inventory Your Computer Before installing FreeBSD you should attempt to inventory the components in your computer. The FreeBSD installation routines will show you the components (hard disks, network cards, CDROM drives, and so forth) with their model number and manufacturer. FreeBSD will also attempt to determine the correct configuration for these devices, which includes information about IRQ and IO port usage. Due to the vagaries of PC hardware this process is not always completely successful, and you may need to correct FreeBSD's determination of your configuration. If you already have another operating system installed, such as Windows, or Linux, it is a good idea to use the facilities provided by those operating systems to see how your hardware is already configured. If you are really not sure what settings an expansion card is using you may find it printed on the card itself. Popular IRQ numbers are 3, 5, and 7, and IO port addresses are normally written as hexadecimal numbers, such as 0x330. We recommend you print or write down this information before installing FreeBSD. It may help to use a table, like this; Sample Device Inventory Device Name IRQ IO port(s) Notes First hard disk N/A N/A 4GB, made by Seagate, first IDE master CDROM N/A N/A First IDE slave Second hard disk N/A N/A 2GB, made by IBM, second IDE master First IDE controller 14 0x1f0 Network card N/A N/A Intel 10/100 Modem N/A N/A 3Com 56K faxmodem, on COM1: …
Backup Your Data If the computer you will be installing FreeBSD on contains valuable data then ensure you have it backed up, and that you have tested the backups before installing FreeBSD. The FreeBSD installation routine will prompt you several times before writing any data to your disk, but once that process has started it can not be undone. Decide Where to Install FreeBSD If you want FreeBSD to use all your disk then there is nothing more to concern yourself with at this point, and you can skip to the next section.. However, if you need FreeBSD to co-exist with other operating systems then you need to have a rough understanding of how data is laid out on the disk, and how this affects you. A PC disk can be divided in to discrete chunks. These chunks are called partitions. By design, the PC only supports four partitions per disk. These partitions are called primary partitions. To work around this limitation, and allow more than four partitions, a new partition type was created, the extended partition. A disk may contain only one extended partition. Special partitions, called logical partitions, can be created inside this extended partition. Each partition has a partition ID, which is a number, used to identify the type of data on the partition. FreeBSD partitions have the partition ID 165. In general, each operating system that you use will identify partitions in a particular way. For example, DOS, and its descendants, like Windows, assign each primary and logical partition a drive letter, starting with C:. FreeBSD must be installed in to a primary partition. FreeBSD can keep all its data, including any files that you create, on this one partition. However, if you have multiple disks then you can create a FreeBSD partition on all, or some, of them. When you install FreeBSD you must have one partition available. This might be a blank partition that you have prepared, or it might be an existing partition that contains data that you no longer care about. If you are already using all the partitions on all your disks then you will have to free one of them for FreeBSD to use, using the tools provided by the other operating systems you use (e.g., fdisk on DOS or Windows). If you have a spare partition then you can use that. However, you may need to shrink one or more of your existing partitions first. A minimal installation of FreeBSD takes as little as 100MB of disk space. However, that is a very minimal install, leaving almost no space for your own files. A more realistic minimum is 250MB without a graphical environment, and 350MB or more if you want a graphical user interface. If you intend to install a lot of third party software as well then you will need more space. You can use a commercial tool such as Partition Magic to resize your partitions to make space for FreeBSD. The tools directory on the CDROM contains two free software tools which can carry out this task, FIPS and PResizer. Documentation for both of these is in the same directory. Incorrect use of these tools can delete the data on your disk. Be sure that you have recent, working backups before using them. Using an existing partition unchanged Suppose that you have a computer with a single 4GB disk, that already has a version of Windows installed, and you have split the disk in to two drive letters, C: and D:, each of which is 2GB in size. You have 1GB of data on C:, and 0.5GB of data on D:. This means that your disk has two partitions on it, one per drive letter. You can copy all your existing data from D: to C:, which will free up the second partition, ready for FreeBSD. Shrinking an existing partition Suppose that you have a computer with a single 4GB disk, that already has a version of Windows installed. When you installed Windows you created one large partition, giving you a C: drive that is 4GB in size. You are currently using 1.5GB of space, and want FreeBSD to have 2GB of space. In order to install FreeBSD you will need to either: Back up your Windows data, and then reinstall Windows, asking for a 2GB partition at install time. Use one of the tools such as Partition Magic, described above, to shrink your Windows partition. Collect Your Network Configuration Details If you intend to connect to a network as part of your FreeBSD installation (e.g., if you will be installing from an FTP site, or an NFS server) then you need to know your network configuration. You will be prompted for this information during the installation so that FreeBSD can connect to the network to complete the install. Connecting to an Ethernet Network, or Cable/DSL Modem If you connect to an Ethernet network, or you have an Internet connection via cable or DSL then you will need the following information: IP address. IP address of the default gateway. Hostname. DNS server IP addresses. If you do not know this information then ask your system administrator or service provider. They may say that this information is assigned automatically, using DHCP. If so, make a note of this. Connecting Using a Modem If you dial up to an ISP using a regular modem then you can still install FreeBSD over the Internet, it will just take a very long time. You will need to know: The phone number to dial for your ISP. The COM: port your modem is connected to. The username and password for your ISP account. Check for FreeBSD Errata Although the FreeBSD project strives to ensure that each release of FreeBSD is as stable as possible, bugs do occasionally creep in to the process. On very rare occasions those bugs affect the installation process. As these problems are discovered and fixed they are noted in the FreeBSD Errata, posted on the FreeBSD web site. You should check the errata before installing to make sure that there are no late-breaking problems which you should be aware of. Information about all the releases, including the errata for each release, can be found at http://www.FreeBSD.org/releases/index.html. Prepare the Boot Discs FreeBSD can be installed from a number of different media; CDROM, DVD, FTP (both anonymous and non-anonymous), NFS, tape, or an existing MS-DOS partition. If you have FreeBSD on CDROM or DVD, and your computer allows you to boot from the CDROM or DVD (typically a BIOS option called Boot Order or similar) then you can skip this section. The FreeBSD CDROM and DVD images are bootable, and can be used to install FreeBSD without any other special preparation. The FreeBSD installation process is started by booting your computer in to the FreeBSD installer—it is not a program you run from within another operating system. To do this you must create some floppy disks that can be booted from, and then boot from them. If you are not installing directly from CDROM, DVD, or FTP then you are probably preparing your own installation media (e.g., an MS-DOS partition), which must be prepared before you install FreeBSD. This is a slightly more advanced, and infrequent activity, and is documented in . This includes the scenario where you want to create your own FTP site on your own network so that other computers can use your site as a FreeBSD FTP installation site. Acquire the Boot Floppy Images The boot discs are available on your installation media, and can also be downloaded from the ftp://ftp.FreeBSD.org/pub/FreeBSD/releases/i386/&rel.current;-RELEASE/floppies/ directory. The floppy images have a .flp extension. The floppies/ directory contains a number of different images, and the ones you will need to use depends on the version of FreeBSD you are installing, and in some cases, the hardware you are installing to. In most cases you will need two files, kern.flp and mfsroot.flp, but check README.TXT in the same directory to be sure. Your FTP program must use binary mode to download these disk images. Some web browsers have been known to use text (or ASCII) mode, which will be apparent if you can not boot from the disks. Prepare the Floppy Disks You must prepare one floppy disk per image file you had to download. It is imperative that these disks are free from defects. The easiest way to test this is to format the disks for yourself. Do not trust pre-formatted floppies. If you try to install FreeBSD and the installation program crashes, freezes, or otherwise misbehaves one of the first things to suspect is the floppies. Try writing the floppy image files to some other disks, and try again. Write the Image Files to the Floppy Disks. The .flp files are not regular files you copy to the disk. Instead, they are images of the complete contents of the disk. This means that you can not use commands like DOS' copy to write the files. Instead, you must use specific tools to write the images directly to the disk. DOS If you are creating the floppies on a computer running DOS/Windows then we provide a tool to do this called fdimage. If you are using the floppies from the CDROM, and your CDROM is the E: drive then you would run this: E:\> tools\fdimage floppies\kern.flp A: Repeat this command for each .flp file, replacing the floppy disk each time, and being sure to label the disks with the name of the file that you copied to them. Adjust the command line as necessary, depending on where you have placed the .flp files. If you do not have the CDROM then fdimage can be downloaded from the tools directory on the FreeBSD FTP site. If you are writing the floppies on a Unix system (such as another FreeBSD system) you can use the &man.dd.1; command to write the image files directly to disk. On FreeBSD you would run: &prompt.root; dd if=kern.flp of=/dev/fd0 On FreeBSD /dev/fd0 refers to the first floppy disk (the A: drive). /dev/fd1 would be the B: drive, and so on. Other Unix variants might have different names for the floppy disk devices, and you will need to check the documentation for the system as necessary. You are now ready to start installing FreeBSD. Starting the Installation By default, the installation will not make any changes to your disk(s) until you see the following message. Last Chance: Are you SURE your want continue the installation? If you're running this on a disk with data you wish to save then WE STRONGLY ENCOURAGE YOU TO MAKE PROPER BACKUPS before proceeding! We can take no responsibility for lost disk contents! The install can be exited at any time prior to the final warning without changing the contents of the hard drive. If you are concerned that you have configured something incorrectly you can just turn the computer off before this point, and no damage will be done. Booting Start with your computer turned off. Turn on the computer. As it starts it should display an option to enter the system set up menu, or BIOS, commonly reached by keys like F2, F10, Del, or Alt S . Use whichever keystroke is indicated on screen. In some cases your computer may display a graphic while it starts. Typically, pressing Esc will dismiss the graphic and allow you to see the necessary messages. Find the setting that controls which devices the system boots from. This is commonly shown as a list of devices, such as Floppy, CDROM, First Hard Disk, and so on. If you needed to prepare boot floppies then make sure that the floppy disk is selected. If you are booting from the CDROM then make sure that that is selected instead. In case of doubt you should consult the manual that came with your computer, and/or its motherboard. Make the change, then save, and exit. The computer should now restart. If you needed to prepare boot floppies, as described in then one of them will be the first boot disc, probably the one containing kern.flp. Put this disc in your floppy drive. If you are booting from CDROM then you will need to turn on the computer, and insert the CDROM at the first opportunity. If your computer starts up as normal, and loads your existing operating system then either: The disks were not inserted early enough in the boot process. Leave them in, and try restarting your computer. The BIOS changes earlier did not work correctly. You should redo that step until you get the right option. FreeBSD will start to boot. If you are booting from CDROM you will see a display similar to this: Verifying DMI Pool Data ........ Boot from ATAPI CD-ROM : 1.

Booting [kernel] in 9 seconds... _ Either wait ten seconds, or press Enter. This will then launch the kernel configuration menu. Kernel Configuration The kernel is the core of the operating system. It is responsible for many things, including access to all the devices you may have on your system, such as hard disks, network cards, sound cards, and so on. Each piece of hardware supported by the FreeBSD kernel has a driver associated with it. Each driver has a two or three letter name, such as sa for the SCSI sequential access driver, or sio for the Serial I/O driver (which manages com ports). When the kernel starts each driver checks the system to see whether or not the hardware it supports exists on your system. If it does then the driver configures the hardware, and makes it available to the rest of the kernel. This checking is commonly referred to as device probing. Unfortunately, it is not always possible to do this in a safe way. Some hardware drivers do not co-exist well together, and probing for one piece of hardware can sometimes leave another piece of hardware in an inconsistent state. This is a basic limitation of the design of the PC. Many older devices are what is called ISA devices—as opposed to PCI devices. The ISA specification requires each device to have some information hard coded in to it, typically the Interrupt Request Line number (IRQ) and IO port address that the driver uses. This information is commonly set by using physical jumpers on the card, or by using a DOS based utility. This was often a source of problems, because it was not possible to have two devices that shared the same IRQ or port address. Newer devices follow the PCI specification, which does not require this, as the devices are supposed to cooperate with the BIOS, and be told which IRQ and IO port addresses to use. If you have any ISA devices in your computer then FreeBSD's driver for that device will need to be configured with the IRQ and port address that you have set the card to. This is why carrying out an inventory of your hardware (see ) can be so useful. Unfortunately, the default IRQs and memory ports used by some drivers clash. This is because some ISA devices are shipped with IRQs or memory ports that clash. The defaults in FreeBSD's drivers are deliberately set to mirror the manufacturer's defaults, so that, out of the box, as many devices as possible will work. This is almost never an issue when running FreeBSD day-to-day. Your computer will not normally contain two pieces of hardware that clash, because then one of them would not work (irrespective of the operating system you are using). It becomes an issue when you are installing FreeBSD for the first time because the kernel used to carry out the install has to contain as many drivers as possible, so that as many different hardware configurations can be supported as possible. This means that some of those drivers will have conflicting configurations. The devices are probed in a strict order, and if you own a device that is probed late in the process, but that an earlier probe conflicted with, then your hardware might not function, or be probed correctly when you install FreeBSD. Because of this, the first thing you have the opportunity to do when installing FreeBSD is look at the list of drivers that are configured in to the kernel, and either disable some of them, if you do not own that device, or confirm (and alter) the driver's configuration if you do own the device but the defaults are wrong. That probably sounds much more complicated than it actually is. shows the first kernel configuration menu. We recommend that you choose the Start kernel configuration in full-screen visual mode option, as it presents the easiest interface for the new user.
Kernel Configuration Menu
The kernel configuration screen () is then divided in to four sections. A collapsible list of all the drivers that are currently marked as active, subdivided in to groups such as Storage, and Network. Each driver is shown as a description, its two three letter driver name, and the IRQ and memory port used by that driver. In addition, if an active driver conflicts with another active driver then CONF is shown next to the driver name. This section also shows the total number of conflicting drivers that are currently active. Drivers that have been marked inactive. They remain in the kernel, but they will not probe for their device when the kernel starts. These are subdivided in to groups in the same way as the active driver list. More detail about the currently selected driver, including its IRQ and memory port address. Information about the keystrokes that are valid at this point in time.
The Kernel Device Configuration Visual Interface
At this point there will always be conflicts listed. Do not worry about this, it is to be expected; all the drivers are enabled, and as has already been explained, some of them will conflict with one another. You now have to work through the list of drivers, resolving the conflicts. Resolving Driver Conflicts Press X. This will completely expand the list of drivers, so you can see all of them. You will need to use the arrow keys to scroll back and forth through the active driver list. shows the result of pressing X.
Expanded Driver List
Disable all the drivers for devices that you do not have. To disable a driver, highlight it with the arrow keys and press Del. The driver will be moved to the Inactive Drivers list. If you inadvertently disable a device that you need then press Tab to switch to the Inactive Drivers list, select the driver that you disabled, and press Enter to move it back to the active list. Do not disable sc0. This controls the screen, and you will need this unless you are installing over a serial cable. Only disable atkbd0 if you are using a USB keyboard. If you have a normal keyboard then you must keep atkbd0. If there are no conflicts listed then you can skip this step. Otherwise, the remaining conflicts need to be examined. If they do not have the indication of an "allowed conflict" in the message area, then either the IRQ/address for device probe will need to be changed, or the IRQ/address on the hardware will need to be changed. To change the driver's configuration for IRQ and IO port address, select the device and press Enter. The cursor will move to the third section of the screen, and you can change the values. You should enter the values for IRQ and port address that you discovered when you made your hardware inventory. Press Q to finish editing the device's configuration and return to the active driver list. If you are not sure what these figures should be then you can try using -1. Some FreeBSD drivers can safely probe the hardware to discover what the correct value should be, and a value of -1 configures them to do this. The procedure for changing the address on the hardware varies from device to device. For some devices you may need to physically remove the card from your computer and adjust jumper settings or DIP switches. Other cards may have come with a DOS floppy that contains the programs used to reconfigure the card. In any case, you should refer to the documentation that came with the device. This will obviously entail restarting your computer, so you will need to boot back in to the FreeBSD installation routine when you have reconfigured the card. When all the conflicts have been resolved the screen will look similar to .
Driver Configuration With No Conflicts
As you can see, the active driver list is now much smaller, with only drivers for the hardware that actually exists being listed. You can now save these changes, and move on to the next step of the install. Press Q to quit the device configuration interface. This message will appear. Save these parameters before exiting? ([Y]es/[N]o/[C]ancel) Answer Y to save the parameters and the probing will start. After displaying the probe results in white on black text Sysinstall will start, and display its main menu ().

Reviewing the Device Probe Results The last few hundred lines that have been displayed on screen are stored, and can be reviewed. To review the buffer, press Scroll Lock. This turns on scrolling in the display. You can then use the arrow keys, or PageUp and PageDown to view the results. Press Scroll Lock again to stop scrolling, Do this now, to review the text that scrolled off the screen when the kernel was carrying out the device probes. You will see text similar to , although the precise text will differ depending on the devices that you have in your computer.

Check the probe results carefully to make sure that FreeBSD found all the devices you expected. If a device was not found then it will be listed as missing. If the device's driver required configuring with the IRQ and port address then you should check that you entered them correctly. If you need to make changes to the UserConfig device probing, its easy to exit the sysinstall program and start over again. Its also a good way to become more familiar with the process.
Select Sysinstall Exit
Use the arrow keys to select Exit Install from the Main Install Screen menu. The following message will display: User Confirmation Requested Are you sure you wish to exit? The system will reboot (be sure to remove any floppies from the drives). [ Yes ] No The install program will start again if the CDROM is left in the drive and [Yes] is selected. If you are booting from floppies it will be necessary to remove the mfs.root floppy and replace it with kern.flp before rebooting. Introducing Sysinstall Sysinstall is the installation application provided by the FreeBSD Project. It is text based, and is divided in to a number of menus and screens that you can use to configure and control the installation process. The Sysinstall menu system is controlled by the arrow keys, Enter, Space. and other keys. A detailed description of these keys, and what they do, is contained in sysinstall's usage information. To review this information, ensure that the Usage entry is highlighted and that the [Select] button is selected, as shown in , then press Enter. The instructions for using the menu system will be displayed. After reviewing them, press Enter to return to the Main Menu.

Allocating Disk Space Your first task is to allocate disk space for FreeBSD, and label that space so that Sysinstall can prepare it. In order to do this you need to know how FreeBSD expects to find information on the disk. Disk Organization The smallest unit of organization that FreeBSD uses to find files is the filename. Filenames are case-sensitive, which means that readme.txt and README.TXT are two separate files. FreeBSD does not use the extension (.txt) of a file to determine whether the file is program, or a document, or some other form of data. Files are stored in directories. A directory may contain no files, or it may contain many hundreds of files. A directory can also contain other directories, allowing you to build up a hierarchy of directories within one another. This makes it much easier to organize your data. Files and directories are referenced by giving the file or directory name, followed by a forward slash, /, followed by any other directory names that are necessary. If you have directory foo, which contains directory bar, which contains the file readme.txt, then the full name, or path to the file is foo/bar/readme.txt. Directories and files are stored in a filesystem. Each filesystem contains exactly one directory at the very top level, called the root directory for that filesystem. This root directory can then contain other directories. So far this is probably similar to any other operating system you may have used. There are a few differences; for example, DOS uses \ to separate file and directory names, while MacOS uses :. FreeBSD does not use drive letters, or other drive names in the path. You would not write c:/foo/bar/readme.txt on FreeBSD. Instead, one filesystem is designated the root filesystem. The root filesystem's root directory is referred to as /. Every other filesystem is then mounted under the root filesystem. No matter how many disks you have on your FreeBSD system, every directory appears to be part of the same disk. Suppose you have three filesystems, called A, B, and C. Each filesystem has one root directory, which contains two other directories, called A1, A2 (and likewise B1, B2 and C1, C2). Call A the root filesystem. If you used the ls command to view the contents of this directory you would see two subdirectories, A1 and A2. The directory tree looks like this. / | +--- A1 | `--- A2 A filesystem must be mounted on to a directory in another filesystem. So now suppose that you mount filesystem B on to the directory A1. The root directory of B replaces A1, and the directories in B appear accordingly. / | +--- A1 | | | +--- B1 | | | `--- B2 | `--- A2 Any files that are in the B1 or B2 directories can be reached with the path /A1/B1 or /A1/B2 as necessary. Any files that were in /A1 have been temporarily hidden. They will reappear if B is unmounted from A. If B had been mounted on A2 then the diagram would look like this; / | +--- A1 | `--- A2 | +--- B1 | `--- B2 and the paths would be /A2/B1 and /A2/B2 respectively. Filesystems can be mounted on top of one another. Continuing the last example, the C filesystem could be mounted on top of the B1 directory in the B filesystem, leading to this arrangement. / | +--- A1 | `--- A2 | +--- B1 | | | +--- C1 | | | `--- C2 | `--- B2 Or C could be mounted directly on to the A filesystem, under the A1 directory. / | +--- A1 | | | +--- C1 | | | `--- C2 | `--- A2 | +--- B1 | `--- B2 If you are familiar with DOS, this is similar, although not identical, to the join command. This is not normally something you need to concern yourself with. Typically you create filesystems when installing FreeBSD and decide where to mount them, and then never change them unless you add a new disk. It is entirely possible to have one large root filesystem, and not need to create any others. There are some drawbacks to this approach, and one advantage. Benefits of multiple filesystems Different filesystems can have different mount options. For example, with careful planning, the root filesystem can be mounted read-only, making it impossible for you to inadvertently delete or edit a critical file. FreeBSD automatically optimizes the layout of files on a filesystem, depending on how the filesystem is being used. So a filesystem that contains many small files that are written frequently will have a different optimization to one that contains fewer, larger files. By having one big filesystem this optimization breaks down. FreeBSD's filesystems are very robust should you lose power. However, a power loss at a critical point could still damage the structure of the filesystem. By splitting your data over multiple filesystems it is more likely that the system will still come up, making it easier for you to restore from backup as necessary. Benefit of a single filesystem Filesystems are a fixed size. If you create a filesystem when you install FreeBSD and give it a specific size, you may later discover that you need to make the partition bigger. This is not easily accomplished without backing up, recreating the filesystems with the size, and then restoring. FreeBSD 5.0 will feature a new command, growfs, which will make it possible to increase the size of a filesystem on the fly, removing this limitation. Filesystems are contained in partitions. This does not have the same meaning as the earlier usage of the term partition in this chapter, because of FreeBSD's Unix heritage. Each partition is identified by a letter, a through to h. Each partition can only contain one filesystem, which means that filesystems are often described by either their typical mount point on the root filesystem, or the letter of the partition they are contained in. FreeBSD also uses disk space for swap space. Swap space provides FreeBSD with virtual memory. This allows your computer to behave as though it has much more memory than it actually does. When FreeBSD runs out of memory it moves some of the data that is not currently being used to the swap space, and moves it back in (moving something else out) when it needs it. Some partitions have certain conventions associated with them. Partition Convention a Normally contains the root filesystem b Normally contains swap space c Normally the same size as the enclosing slice. This allows utilities that need to work on the entire slice (for example, a bad block scanner) to work on the c partition. You would not normally create a filesystem on this partition. d Partition d used to have a special meaning associated with it, although that is now gone. To this day, some tools may operate oddly if told to work on partition d, so Sysinstall will not normally create partition d. Each partition-that-contains-a-filesystem is stored in what FreeBSD calls a slice. Slice is FreeBSD's term for what were earlier called partitions, and again, this is because of FreeBSD's Unix background. Slices are numbered, starting at 1, through to 4. Finally, each disk on the system is identified. A disk name starts with a code that indicates the type of disk, and then a number, indicating which disk it is. Unlike slices, disk numbering starts at 0. Common codes that you will see are listed in . When referring to a partition FreeBSD requires that you also name the slice and disk that contains the partition, and when referring to a slice you should also refer to the disk name. Do this by listing the disk name, s, the slice number, and then the partition letter. Examples are shown in . shows a conceptual model of the disk layout that should help make things clearer. In order to install FreeBSD you must first configure the disk slices, then create partitions within the slice you will use for FreeBSD, and then create a filesystem (or swap space) in each partition, and decide where that filesystem will be mounted. Disk Device Codes Code Meaning ad ATAPI (IDE) disk da SCSI direct access disk acd ATAPI (IDE) CDROM cd SCSI CDROM fd Floppy disk
Sample Disk, Slice, and Partition Names Name Meaning ad0s1a The first partition (a) on the first slice (s1) on the first IDE disk (ad0). da1s2e The fifth partition (e) on the second slice (s2) on the second SCSI disk (da1). Conceptual Model of a Disk This diagram shows FreeBSD's view of the first IDE disk attached to the system. Assume that the disk is 4GB in size, and contains two 2GB slices (DOS partitions). The first slice contains a DOS disk, C:, and the second slice contains a FreeBSD installation. The FreeBSD installation has three partitions, and a swap partition. The three partitions will each hold a filesystem. Partition a will be used for the root filesystem, e for the /var directory hierarchy, and f for the /usr directory hierarchy. .-----------------. --. | | | | DOS / Windows | | : : > First slice, ad0s1 : : | | | | :=================: ==: --. | | | Partition a, mounted as / | | | > referred to as ad0s2a | | | | | :-----------------: ==: | | | | Partition b, used as swap | | | > referred to as ad0s2b | | | | | :-----------------: ==: | Partition c, no | | | Partition e, used as /var > filesystem, all | | > referred to as ad0s2e | of FreeBSD slice, | | | | ad0s2c :-----------------: ==: | | | | | : : | Partition f, used as /usr | : : > referred to as ad0s2f | : : | | | | | | | | --' | `-----------------' --' Creating Slices using FDisk No changes you make at this point will be written to the disk. If you think you have made a mistake and want to start again you can use the menus to exit Sysinstall and try again. If you get confused and can not see how to exit you can always turn your computer off. After choosing to begin a standard installation in Sysinstall you will be shown this message. Message In the next menu, you will need to set up a DOS-style ("fdisk") partitioning scheme for your hard disk. If you simply wish to devote all disk space to FreeBSD (overwriting anything else that might be on the disk(s) selected) then use the (A)ll command to select the default partitioning scheme followed by a (Quit. If you wish to allocate only free space to FreeBSD, move to a partition marked "unused" and use the (C)reate command. [ OK ] [ Press enter to continue ] Press Enter as instructed. You will then be shown a list of all the hard drives that the kernel found when it carried out the device probes. shows an example from a system with two IDE disks. They have been called ad0 and ad2.
- Select Drive for FDISK + Select Drive for FDisk
You might be wondering why ad1 is not listed here. Why has it been missed? Consider what would happen if you had two IDE hard disks, one as the master on the first IDE controller, and one as the master on the second IDE controller. If FreeBSD numbered these as it found them, as ad0 and ad1 then everything would work. But if you then added a third disk, as the slave device on the first IDE controller, it would now be ad1, and the previous ad1 would become ad2. Because device names (such as ad1s1a) are used to find filesystems, you may suddenly discover that some of your filesystems no longer appear correctly, and you would need to change your FreeBSD configuration. To work around this, the kernel can be configured to name IDE disks based on where they are, and not the order in which they were found. With this scheme the master disk on the second IDE controller will always be ad2, even if there are no ad0 or ad1 devices. This configuration is the default for the FreeBSD kernel, which is why this display shows ad0 and ad2. The machine on which this screenshot was taken had IDE disks on both master channels of the IDE controllers, and no disks on the slave channels. You should select the disk on which you want to install FreeBSD, and then press OK. FDisk will start, with a display similar to that shown in . The FDisk display is broken in to three sections. The first section, covering the first two lines of the display, shows details about the currently selected disk, including its FreeBSD name, the disk geometry, and the total size of the disk. The second section shows the slices that are currently on the disk, where they start and end, how large they are, the name FreeBSD gives them, and their description and sub-type. This example shows two small unused slices, which are artifacts of disk layout schemes on the PC. It also shows one large FAT slice, which almost certainly appears as C: in DOS / Windows, and an extended slice, which may contain other drive letters for DOS / Windows. The third section shows the commands that are available in FDisk.
Typical Fdisk Partitions Before Editing
What you do now will depend on how you want to slice up your disk. If you want to use FreeBSD for the entire disk (which will delete all the other data on this disk when you confirm that you want Sysinstall to continue later in the installation process) then you can press A, which corresponds to the Use Entire Disk option. The existing slices will be removed, and replaced with a small area flagged as unused (again, an artifact of PC disk layout), and then one large slice for FreeBSD. If you do this then you should then select the newly created FreeBSD slice using the arrow keys, and press S to mark the slice as being bootable. The screen will then look very similar to . Note the A in the Flags column, which indicates that this slice is active, and will be booted from. If you will be deleting an existing slice to make space for FreeBSD then you should select the slice using the arrow keys, and then press D. You can then press C, and be prompted for size of slice you want to create. Enter the appropriate figure and press Enter. If you have already made space for FreeBSD (perhaps by using a tool such as Partition Magic) then you can press C to create a new slice. Again, you will be prompted for the size of slice you would like to create.
Fdisk Partition Using Entire Disk
When finished, press Q. Your changes will be saved in Sysinstall, but will not yet be written to disk. Install a Boot Manager You now have the option to install a boot manager. In general, you should choose to install the FreeBSD boot manager if: You have more than one drive, and have installed FreeBSD on to a drive other than the first one. You have installed FreeBSD alongside another operating system on the same disk, and you want to choose whether to start FreeBSD or the other operating system when you start the computer. Make your choice, and then select [OK] and press Enter.
Sysinstall Boot Manager Menu
The help screen, reached by pressing F1, discusses the problems that can be encountered when trying to share the hard disk between operating systems. Creating Slices on Another Drive If there is more than one drive, it will return to the Select Drives screen after the boot manager selection. If you wish to install FreeBSD on to more than one disk than you can select another disk here, and repeat the slice process using FDisk,
Exit Select Drive
Make sure [ OK ] is highlighted, then press Enter to continue with the installation. Creating Partitions using <application>Disklabel</application> You must now create some partitions inside each slice that you have just created. Remember that each partition is lettered, from a through to h, and that partitions b, c, and d have conventional meanings that you should adhere to. Certain applications can benefit from particular partition schemes, especially if you are laying out partitions across more than one disk. However, for this, your first FreeBSD installation, you do not need to give too much thought to how you partition the disk. It is more important that you install FreeBSD and start learning how to use it. You can always re-install FreeBSD to change your partition scheme when you are more familiar with the operating system. This scheme features four partitions—one for swap space, and three for filesystems. Partition Layout for First Disk Partition Filesystem Size Description a / 64MB This is the root file system. Every other filesystem will be mounted somewhere under this one. 64MB is a reasonable size for this filesystem. You will not be storing too much data on it, as a regular FreeBSD install will put about 40MB of data here. The remaining space is for temporary data, and also leaves expansion space if future versions of FreeBSD need more space in / b N/A 2-3 x RAM The system's swap space is kept on this partition. Choosing the right amount of swap space can be a bit of an art. A good rule of thumb is that you should have two or three times the amount of RAM as swap space. So if you have 64MB of RAM then you should have between 128MB and 196MB of swap. You should also have at least 64MB of swap, so if you have less than 32MB of RAM in your computer then set the swap amount to 64MB.If you have more than one disk then you can put swap space on each disk. FreeBSD will then use each disk for swap, which effectively speeds up the act of swapping. In this case, calculate the total amount of swap you need (e.g., 128MB), and then divide this by the number of disks you have (e.g., two disks) to give the amount of swap you should put on each disk, in this example, 64MB of swap per disk. e /var 50MB The /var directory contains variable length files; log files, and other administrative files. Many of these files are read-from or written-to extensively during FreeBSD's day-to-day running. Putting these files on another filesystem allows FreeBSD to optimise the access of these files without affecting other files in other directories that do not have the same access pattern. f /usr Rest of disk All your other files will typically be stored in /usr, and its subdirectories.
If you will be installing FreeBSD on to more than one disk then you must also create partitions in the other slices that you configured. The easiest way to do this is to create two partitions on each disk, one for the swap space, and one for a filesystem. Partition Layout for Subsequent Disks Partition Filesystem Size Description b N/A See description As already discussed, you can split swap space across each disk. Even though the a partition is free, convention dictates that swap space stays on the b partition. e /diskn Rest of disk The rest of the disk is taken up with one big partition. This could easily be put on the a partition, instead of the e partition. However, convention says that the a partition on a slice is reserved for the filesystem that will be the root (/) filesystem. You do not have to follow this convention, but Sysinstall does, so following it yourself makes the installation slightly cleaner. You can choose to mount this filesystem anywhere; this example suggests that you mount them as directories /diskn, where n is a number that changes for each disk. But you can use another scheme if you prefer.
Having chosen your partition layout you can now create it using Sysinstall. You will see this message. Message Now, you need to create BSD partitions inside of the fdisk partition(s) just created. If you have a reasonable amount of disk space (200MB or more) and don't have any special requirements, simply use the (A)uto command to allocate space automatically. If you have more specific needs or just don't care for the layout chosen by (A)uto, press F1 for more information on manual layout. [ OK ] Press Enter to start the FreeBSD partition editor, called Disklabel. shows the display when you first start Disklabel. The display is divided in to three sections. The first few lines show the name of the disk you are currently working on, and the slice that contains the partitions you are creating (at this point Disklabel calls this the Partition name rather than slice name). This display also shows the amount of free space within the slice; that is, space that was set aside in the slice, but that has not yet been assigned to a partition. The middle of the display shows the partitions that have been created, the name of the filesystem that each partition contains, their size, and some options pertaining to the creation of the filesystem. The bottom third of the screen shows the keystrokes that are valid in Disklabel.
Sysinstall Disklabel Editor
Disklabel can automatically create partitions for you, and assign them default sizes. Try this now, by Pressing A. You will see a display similar to that shown in . Depending on the size of the disk you are using the defaults may or may not be appropriate. This does not matter, as you do not have to accept the defaults.
Sysinstall Disklabel Editor With Auto Defaults
To delete the suggested partitions, and replace them with your own, use the arrow keys to select the first partition, and press D to delete it. Repeat this to delete all the suggested partitions. To create the first partition (a, mounted as /), make sure the disk information at the top of the screen is selected, and press C. A dialog box will appear prompting you for the size of the new partition (as shown in ). You can enter the size as the number of disk blocks you want to use, or, more usefully, as a number followed by either M for megabytes, G for gigabytes, or C for cylinders.
Free Space For Root Partition
The default size shown will create a partition that takes up the rest of the slice. If you are using the partition sizes described earlier then delete the existing figure using Backspace, and then type in 64M, as shown in . Then press OK.
Edit Root Partition Size
Having chosen the partition's size you will then asked whether this partition will contain a filesystem or swap space. The dialog box is shown in . This first partition will contain a filesystem, so check that FS is selected and then press Enter.
Choose The Root Partition Type
Finally, because you are creating a filesystem, you must tell Disklabel where the filesystem is to be mounted. The dialog box is shown in . The root filesystem's mount point is /, so type /, and then press Enter.
Choose The Root Mount Point
The display will then update to show you the newly created partition. You should repeat this procedure for the other partitions. When you create the swap partition you will not be prompted for the filesystem mount point, as swap partitions are never mounted. When you create the final partition, /usr, you can leave the suggested size as is, to use the rest of the slice. Your final FreeBSD DiskLabel Editor screen will appear similar to , although your values chosen may be different. Press Q to finish.
Sysinstall Disklabel Editor
Choosing What To Install Select The Distribution Set Deciding which distribution set to install will depend largely on the intended use of the system and the amount of disk space available. The predefined options range from installing the smallest possible configuration to everything. Those who are new to Unix and/or FreeBSD should almost certainly select one of these canned options. Customizing a distribution set is typically for the more experienced user. Press F1 for more information on the distribution set options and what they contain. When finished reviewing the help, pressing Enter will return to the Select Distributions Menu. If a graphical user interface is desired then a distribution set that is preceded by an X should be chosen. The configuration of XFree86 and selection of a default desktop is part of the post-installation steps. The default XFree86 version installed is the 3.x branch. You should check to see whether your video card is supported at the XFree86 web site. If it is only supported under the 4.x branch, then you will need to install and configure XFree86 4.x after installation. Select a distribution without X and refer to for more information. If compiling a custom kernel is anticipated, select an option which includes the source code. For more information on why a custom kernel should be built or how to build a custom kernel see . Obviously, the most versatile system is one that includes everything. If there is adequate disk space, select All as shown in by using the arrow keys and press Enter. If there is a concern about disk space consider using an option that is more suitable for the situation. Other distributions can be added after installation.
Choose Distributions
Installing The Ports Collection After selecting the desired distribution, an opportunity to install the FreeBSD Ports Collection is presented. The ports collection is an easy and convenient way to install software. The ports collection does not contain the source code necessary to compile the software. It is a collection of files which automates the downloading, compiling and installation. discusses how to use the ports collection. The installation program does not check to see if you have adequate space. Select this option only if you have adequate hard disk space. User Confirmation Requested Would you like to install the FreeBSD ports collection? This will give you ready access to over 5000 ported software packages, at a cost of around 70MB of disk space when "clean" and possibly much more than that if a lot of the distribution tarballs are loaded (unless you have the extra CDs from a FreeBSD CD/DVD distribution available and can mount it on /cdrom, in which case this is far less of a problem). The ports collection is a very valuable resource and well worth having on your /usr partition, so it is advisable to say Yes to this option. For more information on the ports collection & the latest ports, visit: http://www.freebsd.org/ports [ Yes ] No Select [ Yes ] with the arrow keys to install the ports collection or [ No ] to skip this option. Press Enter to continue. The Choose Distributions menu will redisplay.

If satisfied with the options, select Exit with the arrow keys, ensure that [ OK ] is highlighted, and press Enter to continue. Choosing Your Installation Media If Installing from a CDROM, use the arrow keys to highlight Install from a FreeBSD CDROM. Ensure that [ OK ] is highlighted, then press Enter to proceed with the installation. For other methods of installation, select the appropriate option and follow the instructions. Press F1 to display the Online Help for installation media. Press Enter to return to the media selection menu.
Choose Installation Media
FTP Installation Modes installation network FTP There are three FTP installation modes you can choose from: active FTP, passive FTP, or via a HTTP proxy. FTP Active, Install from an FTP server This option will make all FTP transfers use Active mode. This will not work through firewalls, but will often work with older FTP servers that do not support passive mode. If your connection hangs with passive mode (the default), try active! FTP Passive, Install from an FTP server through a firewall FTP Passive mode This option instructs FreeBSD to use Passive mode for all FTP operations. This allows the user to pass through firewalls that do not allow incoming connections on random port addresses. FTP via a HTTP proxy, Install from an FTP server through a http proxy FTP via a HTTP proxy This option instructs FreeBSD to use the HTTP protocol (like a web browser) to connect to a proxy for all FTP operations. The proxy will translate the requests and send them to the FTP server. This allows the user to pass through firewalls that do not allow FTP at all, but offer a HTTP proxy. In this case, you have to specify the proxy in addition to the FTP server. For a proxy FTP server, you should usually give the name of the server you really want as a part of the username, after an @ sign. The proxy server then fakes the real server. For example, assuming you want to install from ftp.FreeBSD.org, using the proxy FTP server foo.bar.com, listening on port 1024. In this case, you go to the options menu, set the FTP username to ftp@ftp.FreeBSD.org, and the password to your email address. As your installation media, you specify FTP (or passive FTP, if the proxy supports it), and the URL ftp://foo.bar.com:1234/pub/FreeBSD. Since /pub/FreeBSD from ftp.FreeBSD.org is proxied under foo.bar.com, you are able to install from that machine (which will fetch the files from ftp.FreeBSD.org as your installation requests them. Committing to the Installation The installation can now proceed if desired. This is also the last chance for aborting the installation to prevent changes to the hard drive.

[ Yes ] No Select [ Yes ] and press Enter to proceed. The installation time will vary according to the distribution chosen and installation media used. There will be a series of messages displayed indicating the status. The installation is complete when the following message is displayed: Message Congratulations! You now have FreeBSD installed on your system. We will now move on to the final configuration questions. For any option you do not wish to configure, simply select No. If you wish to re-enter this utility after the system is up, you may do so by typing: /stand/sysinstall . [ OK ] [ Press enter to continue ] Press Enter to proceed with post-installation configurations. Selecting [ No ] and pressing Enter will abort the installation so no changes will be made to your system. The following message will appear : Message Installation complete with some errors. You may wish to scroll through the debugging messages on VTY1 with the scroll-lock feature. You can also choose "No" at the next prompt and go back into the installation menus to try and retry whichever operations have failed. [ OK ] This message is generated because nothing was installed. Pressing Enter will return to the Main Installation Menu to exit the installation. Post-installation Configuration of various options follows the successful installation. An option can be configured by re-entering the configuration options before booting the new FreeBSD system or after installation using /stand/sysinstall and selecting Configure. Network Device Configuration If you previously configured PPP for an FTP install, this screen will not display and can be configured later as described above. For detailed information on Local Area Networks and configuring FreeBSD as a gateway/router refer to the tutorial PPP- Pendantic PPP Primer.

Domain The name of the domain that your machine is in, e.g. weeble.com for this case. IPv4 Gateway IP address of host forwarding packets to non-local destinations. Fill this in only if the machine is a node on the network. Leave this field blank if the machine is the gateway to the Internet for the network. Name server IP address of your local DNS server. There is no local DNS server on this private local area network so the IP address of the provider's DNS server (208.163.10.2) was used. IPv4 address The IP address to be used for this interface was (192.168.0.1). Netmask The address block being used for this local area network is a Class C block (192.168.0.0 - 192.168.255.255). The default netmask is for a Class C network (255.255.255.0). Extra options to ifconfig Any interface-specific options to ifconfig you would like to add. There were none in this case. Use Tab to select [ OK ] when finished and press Enter. User Confirmation Requested Would you like to Bring Up the ed0 interface right now? [ Yes ] No Choosing [ Yes ] and pressing Enter will bring the machine up on the network and be ready for use after leaving leaving the installation. Configure Internet Services User Confirmation Requested Do you want to configure inetd and the network services that it provides? Yes [ No ] If [ No ] is selected, various services such telnetd will not be enabled. This means that remote users will not be able to telnet into this machine. Local users will be still be able to access remote machines with telnet. These services can be enabled after installation by editing /etc/inetd.conf with your favorite text editor. See for more information. Select [ Yes ] if you wish to configure these services during install. An additional confirmation will display. User Confirmation Requested The Internet Super Server (inetd) allows a number of simple Internet services to be enabled, including finger, ftp and telnetd. Enabling these services may increase risk of security problems by increasing the exposure of your system. With this in mind, do you wish to enable inetd? [ Yes ] No Select [ Yes ] to continue. User Confirmation Requested inetd(8) relies on its configuration file, /etc/inetd.conf, to determine which of its Internet services will be available. The default FreeBSD inetd.conf(5) leaves all services disabled by default, so they must be specifically enabled in the configuration file before they will function, even once inetd(8) is enabled. Note that services for IPv6 must be seperately enabled from IPv4 services. Select [Yes] now to invoke an editor on /etc/inetd.conf, or [No] to use the current settings.

If you have graphics card and monitor information, select [ Yes ] and press Enter to proceed with configuring the X server.
Select Configuration Method Menu
There are several ways to configure the X server. XF86Setup is fully graphical and probably the easiest. Use the arrow keys to select the XF86Setup and press Enter. Message You have configured and been running the mouse daemon. Choose "/dev/sysmouse" as the mouse port and "SysMouse" or "MouseSystems" as the mouse protocol in the X configuration utility. [ OK ] [ Press enter to continue ] The indicates that the mouse daemon previously configured has been detected. Press Enter to continue. Press [Enter] to switch to graphics mode. This may take a while... [ OK ] Press Enter to switch to the graphics mode and continue. It will not try to switch to the graphics mode until Enter is pressed. The screen will go black and then shortly a screen with a large X in the center will appear. Be patient and wait. After a few more moments, the XF86Setup introduction will display. Read all instructions carefully. Press Enter to continue. <application>XF86Setup</application> Overview There are several areas of configuration to be completed. The configuration choices you make will depend on the hardware in the system so only a general overview can be given here. Along the top of the configuration tool there are buttons indicating the areas to be configured. You should be able to use the mouse if it was previously configured and select each item by clicking on it. Review each area and make appropriate selections for your system. <guimenuitem>Mouse</guimenuitem> The mouse is the first item to be configured. If you previously configured your mouse, the mouse daemon will already be running and should indicate SysMouse automatically for the mouse protocol. If you are use a two button mouse, you should also select Emulate3Buttons. There are other settings that can be tweaked if necessary. After completing your selections, click on the Apply and check the mouse actions are working properly. If further adjustment is needed, make them and recheck the operation by clicking on Apply again. When finished, move on to the next item. <guimenuitem>Keyboard</guimenuitem> Select the appropriate keyboard model. The default keyboard is Generic 101-key PC. Select the language layout for your keyboard. The default layout is U.S. English. If you are not using a U.S. keyboard, you may need to additionally select a variant. There are other options under Group Shift/Lock behavior and Control Key Position that can be selected if desired. Generally the default settings are fine. After completing the keyboard configuration, click on Apply and move on to the next item. <guimenuitem>Card</guimenuitem> Click on Read README file for additional help in configuring your video card. Select the appropriate video card from the list using the scrollbar. Clicking on your card will show as Card selected: above the list box. Next, the Detailed Setup was selected just to check details. Typically, if your video card was in the list, no changes will be needed here. When finished, move on to the next item. <guimenuitem>Monitor</guimenuitem> There are two ways to proceed. One method requires that you enter the horizontal and vertical sweep capabilities of your monitor in the text boxes. Choosing one of the monitor options listed that the monitor is the other method. After selecting a listed option, the horizontal and vertical sweep rates that will be used will display. Compare those to your monitor specifications. The monitor must be capable of using those ranges. Do not exceed the ratings of your monitor. Damage could occur. If you have doubts select ABORT and get the information. The remainder of the installation process will be unaffected and configuring the X-Server can be done later using /stand/sysinstall. When finished, move on to the next item. <guimenuitem>Mode</guimenuitem> Select the video mode(s) that you want to use. You can select more than one option. Typically, useful ranges are 640x480, 800x600, and 1024x768 but those are a function of video card capability, monitor size, and eye comfort. Next, select the default color depth you want to use. Your choices are 8bpp, 16bpp, 24bpp, and 32bpp. Select the highest color depth that your video card will support. When finished, move on to the next item. <guimenuitem>Other</guimenuitem> There default settings are reasonable values so you probably won't need to change anything here. The default setting which allows the server to be killed with the hotkey sequence CtrlAlt Backspace should be left on. This can be executed if something is wrong with the server settings and prevent hardware damage. The default setting that allows video mode switching will permit changing of the mode while running X with the hotkey sequence Alt+ or Alt- . Testing the Server Verify all the settings once again and select Done and the following message will display : If you've finished configuring everything press the Okay button to start the X server using the configuration you've selected. If you still wish to configure some things, press one of the buttons at the top and then press "Done" again, when you've finished. After selecting Okay, some messages will briefly appear advising to wait and attempting to start the x-server. This process takes a few moments, so be patient. The screen will go blank for a short period of time and then a screen will appear with the message Congratulations, you've got a running server! If nothing appears or is distorted, kill the x-server using Ctrl Alt Backspace and adjust the settings or revisit them after installation. Running <command>xvidtune</command> The display can be adjusted for height, width, or centering by using xvidtune. There are warnings that improper settings can damage your equipment. Heed them. If in doubt, do not do it. Instead, use the monitor controls to adjust the display for x-windows. There may be some display differences when switching back to text mode, but it is better than damaging equipment. The xvidtune can be ran later using /stand/sysinstall. Read the xvidtune before making any adjustments. Saving Configuration When you are satisfied, the configuration can now be saved. Select Save the configuration and Exit The configuration file will be saved to /etc/XF86Config. Once the configuration is done, the installation program will need to create a link to the server : Do you want to create an 'X' link to the SVGA server? (the link will be created in the directory: /usr/X11R6/bin) Okay? [ Yes ] No Select [ Yes ] and press Enter to create the link. Link created successfully. [ OK ] Press Enter to continue configuration. Select Default X Desktop There are a variety of window managers available. They range from very basic environments to full desktop environments with a large suite of software. Some require only minimal disk space and low memory while others with more features require much more. The best way to determine which is most suitable for you is to try a few different ones. Those are available from the ports collection or as packages and can be added after installation. You can select one of the popular desktops to be installed and configured as the default desktop. This will allow you to start it right after installation.
Select Default Desktop
Use the arrow keys to select a desktop and press Enter. Installation of the selected desktop will proceed. Install Packages The packages are pre-compiled binaries and are a convenient way to install software. Installation of one package is shown for purposes of illustration. Additional packages can also be added at this time if desired. After installation /stand/sysinstall can be used to add additional packages. User Confirmation Requested The FreeBSD package collection is a collection of hundreds of ready-to-run applications, from text editors to games to WEB servers and more. Would you like to browse the collection now? [ Yes ] No Selecting [ Yes ] and pressing Enter will be followed by the Package Selection screens:

When you have finished marking the packages for installation, select [ OK ] and press Enter to return to the Package Selection menu.
Install Packages
Use the arrow keys to select [ Install ] and press Enter. You will then need to confirm that you want to install the packages.
Confirm Package Installation
Selecting [ OK ] and pressing Enter will start the package installation. Installing messages will appear until completed. Make note if there are any error messages. The final configuration continues after packages are installed. Add User/Groups You should add at least one user during the installation so that you can use the system without being logged in as root. The root partition is generally small and running applications as root can quickly fill it. A bigger danger is noted below : User Confirmation Requested Would you like to add any initial user accounts to the system? Adding at least one account for yourself at this stage is suggested since working as the "root" user is dangerous (it is easy to do things which adversely affect the entire system). [ Yes ] No Select [ Yes ] and press Enter to continue with adding a user.
Select Add User
Select Add User with the arrow keys and press Enter.
Add User Information
The following descriptions will appear in the lower part of the screen as the items are selected with Tab to assist with entering the required information. Login ID The login name of the new user (mandatory) UID The numerical ID for this user (leave blank for automatic choice) Group The login group name for this user (leave blank for automatic choice) Password The password for this user (enter this field with care!) Full name The user's full name (comment) Member groups The groups this user belongs to (i.e. gets access rights for) Home directory The user's home directory (leave blank for default) Login shell The user's login shell (leave blank for default). (/bin/sh) The login shell was changed from /bin/sh to /usr/local/bin/bash to use the bash shell that was previously installed as a package. Do not try to use a shell that does not exist or you will not be able to login. The user was also added to the group "wheel" to be able to become a superuser with root privileges. When you are satisfied, press [ OK ] and the User and Group Management menu will redisplay.
Exit User and Group Management
Groups could also be added at this time if specific needs are known. Otherwise, this may be accessed through using /stand/sysinstall after installation is completed. When you are finished adding users, select Exit with the arrow keys and press Enter to continue the installation. Set Root Password Message Now you must set the system manager's password. This is the password you'll use to log in as "root". [ OK ] [ Press enter to continue ] Press Enter to set the root password. The password will need to be typed in twice correctly. Needless to say, make sure you have a way of finding the password if you forget. Changing local password for root. New password : Retype new password : The installation will continue after the password is successfully entered. Exiting Install If you need to configure additional network devices or to do any other configurations, you can do it at this point or after installation with /stand/sysinstall. User Confirmation Requested Visit the general configuration menu for a chance to set any last options? Yes [ No ] Selecting [ No ] with the arrow keys and pressing Enter returns to the Main Installation Menu
Exit Install
Select [X Exit Install] with the arrow keys and press Enter. You will be asked to confirm exiting the installation : User Confirmation Requested Are you sure you wish to exit? The system will reboot (be sure to remove any floppies from the drives). [ Yes ] No Select [ Yes ] and remove floppy if booting from floppy. The CDROM drive is locked until the machine starts to reboot. The CDROM drive is then unlocked and can be removed from drive (quickly). The system will reboot so watch for any error messages that may appear. FreeBSD Bootup If everything went well, you will see messages scroll off the screen and you will arrive at a login prompt. You can view the content of the messages by pressing Scroll-Lock and using PgUp and PgDn. Pressing Scroll-Lock again will return to the prompt. The entire message may not display (buffer limitation) but it can be viewed from the command line after logging in by typing dmesg at the prompt. Login using the username/password you set during installation (rpratt, in this example). Avoid logging in as root except when necessary.

FreeBSD Shutdown It is important to properly shutdown the operating system. Do not just turn off power. First, become a superuser by typing su at the command line and entering the root password. This will work only if the user is a member of the group wheel. Otherwise, login as root and use shutdown -h now. The operating system has halted. Please press any key to reboot. It is safe to turn off the power after the shutdown command has been issued and the message "Please press any key to reboot" appears. If any key is pressed instead of turning off the power switch, the system will reboot. Supported Hardware hardware FreeBSD currently runs on a wide variety of ISA, VLB, EISA, and PCI bus-based PCs with Intel, AMD, Cyrix, or NexGen x86 processors, as well as a number of machines based on the Compaq Alpha processor. Support for generic IDE or ESDI drive configurations, various SCSI controllers, PCMCIA cards, USB devices, and network and serial cards is also provided. FreeBSD also supports IBM's microchannel (MCA) bus. A list of supported hardware is provided with each FreeBSD release in the FreeBSD Hardware Notes. This document can usually be found in a file named HARDWARE.TXT, in the top-level directory of a CDROM or FTP distribution or in sysinstall's documentation menu. It lists, for a given architecture, what hardware devices are known to be supported by each release of FreeBSD. Troubleshooting installation troubleshooting The following section covers basic installation troubleshooting, such as common problems people have reported. There are also a few questions and answers for people wishing to dual-boot FreeBSD with MS-DOS. What to Do If Something Goes Wrong... Due to various limitations of the PC architecture, it is impossible for probing to be 100% reliable, however, there are a few things you can do if it fails. Check the Hardware Notes document for your version of FreeBSD to make sure your hardware is supported. If your hardware is supported and you still experience lock-ups or other problems, reset your computer, and when the visual kernel configuration option is given, choose it. This will allow you to go through your hardware and supply information to the system about it. The kernel on the boot disks is configured assuming that most hardware devices are in their factory default configuration in terms of IRQs, IO addresses, and DMA channels. If your hardware has been reconfigured, you will most likely need to use the configuration editor to tell FreeBSD where to find things. It is also possible that a probe for a device not present will cause a later probe for another device that is present to fail. In that case, the probes for the conflicting driver(s) should be disabled. Do not disable any drivers you will need during the installation, such as your screen (sc0). If the installation wedges or fails mysteriously after leaving the configuration editor, you have probably removed or changed something you should not have. Reboot and try again. In configuration mode, you can: List the device drivers installed in the kernel. Change device drivers for hardware that is not present in your system. Change IRQs, DRQs, and IO port addresses used by a device driver. After adjusting the kernel to match your hardware configuration, type Q to boot with the new settings. Once the installation has completed, any changes you made in the configuration mode will be permanent so you do not have to reconfigure every time you boot. It is still highly likely that you will eventually want to build a custom kernel. MS-DOS User's Questions and Answers DOS Many users wish to install FreeBSD on PCs inhabited by MS-DOS. Here are some commonly asked questions about installing FreeBSD on such systems. Help, I have no space! Do I need to delete everything first? If your machine is already running MS-DOS and has little or no free space available for the FreeBSD installation, all hope is not lost! You may find the FIPS utility, provided in the tools directory on the FreeBSD CDROM or various FreeBSD FTP sites to be quite useful. FIPS FIPS allows you to split an existing MS-DOS partition into two pieces, preserving the original partition and allowing you to install onto the second free piece. You first defragment your MS-DOS partition using the Windows DEFRAG utility (go into Explorer, right-click on the hard drive, and choose to defrag your hard drive), or Norton Disk Tools. You then must run FIPS. It will prompt you for the rest of the information it needs. Afterwards, you can reboot and install FreeBSD on the new free slice. See the Distributions menu for an estimate of how much free space you will need for the kind of installation you want. Partition Magic There is also a very useful product from PowerQuest called Partition Magic. This application has far more functionality than FIPS, and is highly recommended if you plan to often add/remove operating systems (like me). However, it does cost money, and if you plan to install FreeBSD once and then leave it there, FIPS will probably be fine for you. Can I use compressed MS-DOS filesystems from FreeBSD? No. If you are using a utility such as Stacker(tm) or DoubleSpace(tm), FreeBSD will only be able to use whatever portion of the filesystem you leave uncompressed. The rest of the filesystem will show up as one large file (the stacked/double spaced file!). Do not remove that file or you will probably regret it greatly! It is probably better to create another uncompressed primary MS-DOS partition and use this for communications between MS-DOS and FreeBSD. Can I mount my extended MS-DOS partition? partitions slices Yes. DOS extended partitions are mapped in at the end of the other slices in FreeBSD, e.g., your D: drive might be /dev/da0s5, your E: drive, /dev/da0s6, and so on. This example assumes, of course, that your extended partition is on SCSI drive 0. For IDE drives, substitute ad for da appropriately if installing 4.0-RELEASE or later, and substitute wd for da if you are installing a version of FreeBSD prior to 4.0. You otherwise mount extended partitions exactly like you would any other DOS drive, for example: &prompt.root; mount -t msdos /dev/ad0s5 /dos_d Valentino Vaschetto Contributed by Advanced Installation Guide This section describes how to install FreeBSD in exceptional cases. Installing FreeBSD on a System without a Monitor or Keyboard installation headless (serial console) serial console This type of installation is called a "headless install", because the machine that you are trying to install FreeBSD on either doesnt have a monitor attached to it, or doesnt even have a VGA output. How is this possible you ask? Using a serial console. A serial console is basically using another machine to act as the main display and keyboard for a system. To do this, just follow these steps: Fetch the Right Boot Floppy Images First you will need to get the right disk images so that you can boot into the install program. The secret with using a serial console is that you tell the boot loader to send I/O through a serial port instead of displaying console output to the VGA device and trying to read input from a local keyboard. Enough of that now, let's get back to getting these disk images. You will need to get kern.flp and mfsroot.flp from the floppies directory. Write the Image Files to the Floppy Disks. The image files, such as kern.flp, are not regular files that you copy to the disk. Instead, they are images of the complete contents of the disk. This means that you can not use commands like DOS' copy to write the files. Instead, you must use specific tools to write the images directly to the disk. fdimage If you are creating the floppies on a computer running DOS then we provide a tool to do this called fdimage. If you are using the floppies from the CDROM, and your CDROM is the E: drive then you would run this: E:\> tools\fdimage floppies\kern.flp A: Repeat this command for each .flp file, replacing the floppy disk each time. Adjust the command line as necessary, depending on where you have placed the .flp files. If you do not have the CDROM then fdimage can be downloaded from the tools directory on the FreeBSD FTP site. If you are writing the floppies on a Unix system (such as another FreeBSD system) you can use the &man.dd.1; command to write the image files directly to disk. On FreeBSD you would run: &prompt.root; dd if=kern.flp of=/dev/fd0 On FreeBSD /dev/fd0 refers to the first floppy disk (the A: drive). /dev/fd1 would be the B: drive, and so on. Other Unix variants might have different names for the floppy disk devices, and you will need to check the documentation for the system as necessary. Enabling the Boot Floppies to Boot into a Serial Console Do not try to mount the floppy if it is write-protected mount If you were to boot into the floppies that you just made, FreeBSD would boot into its normal install mode. We want FreeBSD to boot into a serial console for our install. To do this, you have to mount the kern.flp floppy onto your FreeBSD system using the &man.mount.8; command. &prompt.root; mount /dev/fd0 /mnt Now that you have the floppy mounted, you must change into the floppy directory &prompt.root; cd /mnt Here is where you must set the floppy to boot into a serial console. You have to make a file called boot.config containing "/boot/loader -h". All this does is pass a flag to the bootloader to boot into a serial console. &prompt.root; echo "/boot/loader -h" > boot.config Now that you have your floppy configured correctly, you must unmount the floppy using the &man.umount.8; command &prompt.root; cd / &prompt.root; umount /mnt Now you can remove the floppy from the floppy drive Connecting Your Null Modem Cable null-modem cable You now need to connect a null modem cable between the two machines. Just connect the cable to the serial ports of the 2 machines. A normal serial cable will not work here, you need a null modem cable because it has some of the wires inside crossed over. Booting Up for the Install It is now time to go ahead and start the install. Put the kern.flp floppy in the floppy drive of the machine you are doing the headless install on, and power on the machine. Connecting to Your Headless Machine cu Now you have to connect to that machine with &man.cu.1;: &prompt.root; cu -l /dev/cuaa0 That's it! You should be able to control the headless machine through your cu session now. It will ask you to put in the mfsroot.flp, and then it will come up with a selection of what kind of terminal to use. Just select the FreeBSD color console and proceed with your install! Preparing Your Own Installation Media To prevent repititon, FreeBSD disk in this context means a FreeBSD CDROM or DVD that you have purchased, or produced yourself. There may be some situations in which you need to create your own FreeBSD installation media and/or source. This might be physical media, such as a tape, or a source that Sysinstall can use to retrieve the files, such as a local FTP site, or an MS-DOS partition. For example; You have many machines connected to your local network, and one FreeBSD disk. You want to create a local FTP site using the contents of the FreeBSD disk, and then have your machines use this local FTP site instead of needing to connect to the Internet. You have a FreeBSD disk, FreeBSD does not recognise your CD/DVD drive, but DOS/Windows does. You want to copy the FreeBSD installations files to a DOS partition on the same computer, and then install FreeBSD using those files. The computer you want to install on does not have a CD/DVD drive, or a network card, but you can connect a Laplink-style serial or parallel cable to a computer that does. You want to create a tape that can be used to install FreeBSD. Creating a Local FTP Site with a FreeBSD Disk installation network FTP FreeBSD disks are laid out in the same way as the FTP site. This makes it very easy for you to create a local FTP site that can be used by other machines on your network when installing FreeBSD. On the FreeBSD computer that will host the FTP site, ensure that the CDROM is in the drive, and mounted on /cdrom. &prompt.root; mount /cdrom Create an account for anonymous FTP in /etc/passwd. Do this by editing /etc/passwd using &man.vipw.8; and adding this line. ftp:*:99:99::0:0:FTP:/cdrom:/nonexistent Ensure that the FTP service is enabled in /etc/inetd.conf. Anyone with network connectivity to your machine can now chose a media type of FTP and type in ftp://your machine after picking Other in the FTP sites menu during the install. This approach is OK for a machine that is on your local network, and that is protected by your firewall. Offering up FTP services to other machines over the Internet (and not your local network) exposes your computer to the attention of crackers and other undesirables. We strongly recommend that you follow good security practices if you do this. Creating Installation Floppies installation floppies If you must install from floppy disk (which we suggest you do not do), either due to unsupported hardware or simply because you insist on doing things the hard way, you must first prepare some floppies for the installation. At a minimum, you will need as many 1.44MB or 1.2MB floppies as it takes to hold all the files in the bin (binary distribution) directory. If you are preparing the floppies from DOS, then they MUST be formatted using the MS-DOS FORMAT command. If you are using Windows, use Explorer to format the disks (right-click on the A: drive, and select "Format". Do not trust factory pre-formatted floppies. Format them again yourself, just to be sure. Many problems reported by our users in the past have resulted from the use of improperly formatted media, which is why we are making a point of it now. If you are creating the floppies on another FreeBSD machine, a format is still not a bad idea, though you do not need to put a DOS filesystem on each floppy. You can use the disklabel and newfs commands to put a UFS filesystem on them instead, as the following sequence of commands (for a 3.5" 1.44MB floppy) illustrates: &prompt.root; fdformat -f 1440 fd0.1440 &prompt.root; disklabel -w -r fd0.1440 floppy3 &prompt.root; newfs -t 2 -u 18 -l 1 -i 65536 /dev/fd0 Use fd0.1200 and floppy5 for 5.25" 1.2MB disks. Then you can mount and write to them like any other filesystem. After you have formatted the floppies, you will need to copy the files to them. The distribution files are split into chunks conveniently sized so that 5 of them will fit on a conventional 1.44MB floppy. Go through all your floppies, packing as many files as will fit on each one, until you have all of the distributions you want packed up in this fashion. Each distribution should go into a subdirectory on the floppy, e.g.: a:\bin\bin.aa, a:\bin\bin.ab, and so on. Once you come to the Media screen during the install process, select Floppy and you will be prompted for the rest. Installing from an MS-DOS Partition installation from MS-DOS To prepare for an installation from an MS-DOS partition, copy the files from the distribution into a directory on that partition. For example, c:\freebsd. The directory structure of the CDROM or FTP site must be partially reproduced within this directory, so we suggest using the DOS xcopy command if you are copying it from a CD. For example, to prepare for a minimal installation of FreeBSD: C:\> md c:\freebsd C:\> xcopy e:\bin c:\freebsd\bin\ /s C:\> xcopy e:\manpages c:\freebsd\manpages\ /s Assuming that C: is where you have free space and E: is where your CDROM is mounted. If you do not have a CDROM drive, you can download the distribution from ftp.FreeBSD.org. Each distribution is in its own directory; for example, the bin distribution can be found in the &rel.current;/bin directory. For as many distributions you wish to install from an MS-DOS partition (and you have the free space for), install each one under c:\freebsd — the BIN distribution is the only one required for a minimum installation. Creating an Installation Tape installation from QIC/SCSI Tape Installing from tape is probably the easiest method, short of an online FTP install or CDROM install. The installation program expects the files to be simply tarred onto the tape. After getting all of the distribution files you are interested in, simply tar them onto the tape; &prompt.root; cd /freebsd/distdir &prompt.root; tar cvf /dev/rwt0 dist1 ... dist2 When you go to do the installation, you should also make sure that you leave enough room in some temporary directory (which you will be allowed to choose) to accommodate the full contents of the tape you have created. Due to the non-random access nature of tapes, this method of installation requires quite a bit of temporary storage. You should expect to require as much temporary storage as you have stuff written on tape. When starting the installation, the tape must be in the drive before booting from the boot floppy. The installation probe may otherwise fail to find it. Before Installing over a Network installation network serial (SLIP or PPP) installation network parallel (PLIP) installation network Ethernet There are three types of network installations you can do. Serial port (SLIP or PPP), Parallel port (PLIP (laplink cable)), or Ethernet (a standard Ethernet controller (includes some PCMCIA)). The SLIP support is rather primitive, and limited primarily to hard-wired links, such as a serial cable running between a laptop computer and another computer. The link should be hard-wired as the SLIP installation does not currently offer a dialing capability; that facility is provided with the PPP utility, which should be used in preference to SLIP whenever possible. If you are using a modem, then PPP is almost certainly your only choice. Make sure that you have your service provider's information handy as you will need to know it fairly early in the installation process. If you use PAP or CHAP to connect your ISP (in other words, if you can connect to the ISP in Windows without using a script), then all you will need to do is type in dial at the ppp prompt. Otherwise, you will need to know how to dial your ISP using the AT commands specific to your modem, as the PPP dialer provides only a very simple terminal emulator. Please refer to the user-ppp handbook and FAQ entries for further information. If you have problems, logging can be directed to the screen using the command set log local .... If a hard-wired connection to another FreeBSD (2.0-R or later) machine is available, you might also consider installing over a laplink parallel port cable. The data rate over the parallel port is much higher than what is typically possible over a serial line (up to 50kbytes/sec), thus resulting in a quicker installation. Finally, for the fastest possible network installation, an Ethernet adapter is always a good choice! FreeBSD supports most common PC Ethernet cards; a table of supported cards (and their required settings) is provided in the Hardware Notes for each release of FreeBSD. If you are using one of the supported PCMCIA Ethernet cards, also be sure that it is plugged in before the laptop is powered on! FreeBSD does not, unfortunately, currently support hot insertion of PCMCIA cards during installation. You will also need to know your IP address on the network, the netmask value for your address class, and the name of your machine. If you are installing over a PPP connection and do not have a static IP, fear not, the IP address can be dynamically assigned by your ISP. Your system administrator can tell you which values to use for your particular network setup. If you will be referring to other hosts by name rather than IP address, you will also need a name server and possibly the address of a gateway (if you are using PPP, it is your provider's IP address) to use in talking to it. If you want to install by FTP via a HTTP proxy (see below), you will also need the proxy's address. If you do not know the answers to all or most of these questions, then you should really probably talk to your system administrator or ISP before trying this type of installation. Before Installing via NFS installation network NFS The NFS installation is fairly straight-forward. Simply copy the FreeBSD distribution files you want onto a server somewhere and then point the NFS media selection at it. If this server supports only privileged port (as is generally the default for Sun workstations), you will need to set this option in the Options menu before installation can proceed. If you have a poor quality Ethernet card which suffers from very slow transfer rates, you may also wish to toggle the appropriate Options flag. In order for NFS installation to work, the server must support subdir mounts, e.g., if your FreeBSD 3.4 distribution directory lives on:ziggy:/usr/archive/stuff/FreeBSD, then ziggy will have to allow the direct mounting of /usr/archive/stuff/FreeBSD, not just /usr or /usr/archive/stuff. In FreeBSD's /etc/exports file, this is controlled by the . Other NFS servers may have different conventions. If you are getting permission denied messages from the server, then it is likely that you do not have this enabled properly.
